IMPROVEMENT IN CLIPPING-SHEARS.

Specification forming part of Letters Patent No. 119,019, dated September 19, 1871.

Maine, have invented a new and useful Sheep and Horse-Clipping Machine and I hereby declare the following to be a full, clear, and exact description of the same, reference beinghad to the accompanying drawing forming part of this specification, in which- Figure l is a top plan. Fig. 2 is an end view.

A shows an end view of the plate.

Same letters show like parts.

The purpose of my invention is to provide a device for clipping horses and for effecting the same with easel and uniformity. A special description of the device illustrated in the drawing will explain the nature and operation of my invention.

a shows a plate, flat and smooth on the under side, and having the teeth or spurs b projecting laterally from each side thereof'. Upon the upper side is the groove c. Upon the top of this plate slides the piece d with a dovetailed projection to tit into the groove c, also `formed tlaring for this purpose. Extending' from the piece d are the knives c, fitting down closely onto the top ofthe teeth b. The knives are drawn backward and forward by the rod f, and the hair of the animal projecting up between the teeth b is cut by the passage over it of the knives c. The plate c is held upon the arm h, (somewhat bent at i, so as to give the proper position to the plate when being used,) and has aslit, through which works the rodf, as illustrated. The arm h is rigidly attached to the cylinder j, and is somewhat bent at al, if desired, to enable the plate a to be conveniently laid upon the animals skin. The rod f extends into the cylinder, and

purpose of the cylinder and piston is to operate `the cutters c by pressure and exhaustion of air or other fluid, so that either a person can singly manage the cutter while another produces its motion, or one hand can be used to direct the cutter while the other is used to produce the force to move the cutter c. At m is connected a tube, long or short, as the method of operating the piston may be 5 then, by forcing air into the cylinder (as by the downward stroke of a pistonin an air-pump con- `ter c back again.

The

nected with the cylinder j by a tube) the piston l is forced out toward the end of the cylinder j and the cutters c moved correspondingly, and when the piston of the air-pump is lifted the exhaustion of the air in j moves the piston and cut- A person can be stationed at a distance of a few feet and operate a small pump, and another hold the cutter on the animals skin; or a bulb can be used in one hand while the other holds the cutter. Thus thel cutter is operated without that tendency to shaking or disturbance that would ensue with a less easy and uniform method of operating the knives, and in either case at least one handcan be exclusively employed to keep the plate a, properly applied.

I am aware of Letters Patent N o. 61,700, to Philander Anderson, dated February 5, 1867, for a device for a similar purpose, but which presents many and essential points of difference. The motion ofthe piston is not directly comuninicated to the shearer, but indirectly, by means of the slottedlever D. The motion of his shearer is at right angles to the direction of the pistons motion, while in mine the direction of the motion of shearer and piston is the same, which. mode of construction renders the machine much more convenient in use. Furthermore, my device is much more simple, easy of construction, and cheaper than his device. i

I do not claim the construction of a portable sheep-shearing instrument, whereby to be enabled to use air under pressure, so as to operate the engine and perform the required functions. Nor do I claim the combination of the cross-head of the piston-rod of the engine directly with the shear-lever D, (see Letters Patent above referred to,) sol that this lever shall receive a vibrating motion from the piston-rod.

What I claim as my invention, and desire to secure by Letters Patent, is

In combination with the plate a, the piece d and cutters c, rod j' and arm h, the cylinder j and piston Z, the said cutters e to operate directly from and in the same direction with the piston l, as here- GEORGE F. EVANS.
